Waveshare DVK512 Raspberry Pi Expansion Board Previous 
Description
There's no AD/DA function on the Raspberry Pi GPIO interface, this may trouble you in the Pi development. However, it won't be a problem anymore. The High-Precision AD/DA Board allows you to add high-precision AD/DA functions to the Raspberry Pi.
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano. Onboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rate.Onboard DAC8552, 2ch 16bit high-precision DAC.Onboard input interface via pinheaders, for connecting analog signal, the pinout is compatible with Waveshare sensor interface standard, easy to connect various analog sensor modules. Onboard input/output interface via screw terminals, for connecting analog/digital signal. Features AD/DA detect circuit, easy for signal demonstration.
